The City Council here voted late Tuesday to ban certain giant retail stores, dealing a blow to Wal-Mart Stores Inc.’s potential to expand in the nation’s eighth-largest city. The measure, approved on a 5-3 vote, prohibits stores of more than 90,000 square feet that use 10 percent of space to sell groceries and other merchandise that is not subject to sales tax. It takes aim at Wal-Mart Supercenter stores, which average 185,000 square feet and sell groceries.
Mayor Jerry Sanders will veto the ban if the Council reaffirms it on a second vote, which will likely happen in January, said mayoral spokesman Fred Sainz. The Council can override his veto with five votes. “What the Council did tonight was social engineering, not good public policy,” Sainz said.

In other words, the San Diego City Council is voting against middle class and working poor voters but the mayor will defend these people from the politicians.
